ALMA image of the protoplanetary disk around the triple young star GW Orionis

Caption

Three rings are clearly seen in the image. The innermost ring looks almost circular because it is viewed face-on, but the two outer rings are viewed at an angle and appear oval. The central triple stars are not visible in this image.
